Patent FR-2295448-A1 (FR)
Title: Start-up sequencer for cine projector - uses relays and time delays to isolate sound system
Inventor: HOUDELETTE ROGER
IPC: G03B21/32
Filed: 1974-12-19
Abstract: The sequencer for starting up a cinematography projector open circuits the sound track pick-up and short circuits the loud speaker until the arc-lamp has ignited, after which the sound system is reestablished. On manually pressing the start button (CM) or by automatic switching (CA), a voltage (Uc) is applied through two relay coils (Z1, Z2). The capacitances and resistances delay the activation of these relays so that relay coil (Z2) is activated before (Z1). The activation of (Z2) short circuit the loud speaker and open circuits the loud speaker before (Z2) activates. When the latter occurs the power supply to the acr lamp is switched on. The isolation of the sound system prevents interference from this start up being broadcast. With (Z2) activated the power to both (Z1) and (Z2) is cut off, and the sound system is eventually turned on.

Title: Gear linkage for tipping cab - has telescopic gear change shafts and coupling lever to release linkage
IPC: B62D33/073
Filed: 1975-04-02
Abstract: The gear linkage between the cab gear selector lever (6) and the gear box is by means of a hollow shaft (8) which is guided on a coaxial support shaft (9) whose front end is secured to the floor of the cab (1) by a ball joint (10). The gear change movements are transmitted from the gear lever to the shaft by a link (16) which engages the outer shaft using a drive peg (15) linked to the shaft by a coupling plate (11). The front of the link is hinged on the fixed shaft support so that when the cab is tipped the coupling link, and coupling plate are tipped away from the outer shaft. As the cab is dropped again the sloping edges of the coupling plate engage the outer shaft and relocate the gear selector lever in the set gear position.

Title: Removing hydrogen sulphide and mercaptans from effluent gas - with aqs. metal chelate soln., purified by liq. extractant and recycled
Inventor: CAPITAINE MICHEL
IPC: B01D11/04
Filed: 1975-11-05
Abstract: The continuous process comprises contacting the effluent gas and an O2 contg. gas with an aqs. soln. of a polyvalent metal chelate, sepg. the gaseous and liq. phases, and purifying and recycling the liq. contg. the chelate. The novelty is that the liq. is purified with an extractant for S and alkyl disulphides, the extractant being (almost) insoluble in water and of different density from the aqs. soln. of the metal chelate. A suitable extractant is 1,2-dichloroethane. Blockage of the appts. by deposits, formation of foam and degradation of the chelate are avoided. The sulphur and disulphides produced can be recovered in 90-100% purity by simple decantation, evapn., filtration or crystallisation.

Title: Assembly for sterilising dialyser after blood treatment - with integral tubing and pumps for circulating and discharging sterilising fluid
IPC: A61L2/18
Filed: 1975-12-29
Abstract: A dialyser is housed in a vessel within the framework of an assembly. Connected to the dialyser housing by inlet and outlet tubing is a circulation pump which circulates both dialysing solution and sterilising soln. The dialysing soln. and the sterilising fluid are fed into the suction tubing of the pump through a separate supply pipe connected to external sources of the fluids. Also connected to the dialyser are inlet and outlet tubes for the blood supply and return. Leading to a catch pot from the dialyser housing are separate lines for the discharge of the dialysing soln. and sterilising fluid and for draining the housing. This catch pot is on the suction of a pump for discharging the fluids. Connected to the discharge side of the circulating pump is another tube which can be temporarily connected to the blood supply tube to the dialyser. Another line attached to the catch pot can be temporarily connected to the blood return line from the dialyser. On the line connecting into the blood supply pipe is a solenoid valve which is opened when sterilising fluid is to be circulated through the blood passage side of the dialyser. The drain line between dialyser housing and catch pot also has a solenoid valve so that the discharge pump draws. soln. through the dialyser housing and catch pot when this valve is closed. For sterilising dialysers after they have been used for treating a subject's blood. The dialyser can be stored under sterilising soln. and used again for the same subject. Only dialysers that are to be thrown away have to be handled in the non-sterilised condition.
